The influence of oscillations on global existence for a class of semi-linear wave equations
(WILEY-BLACKWELL, 2011)
The goal of this paper is to study the global existence of small data solutions to the Cauchy problem for the nonlinear wave equation u(tt) - a(t)(2) Delta u = u(t)(2) - a(t)(2)vertical bar del u vertical bar(2). In ...

Pilot wave approach to the NRT nonlinear Schrödinger equation
(Elsevier Science, 2014-06)
We investigate the main features of a pilot wave representation of the nonlinear Schrödinger equation recently advanced by Nobre, Rego-Monteiro, and Tsallis (NRT) on the basis of Tsallis q-thermo-statistical formalism. The ...
Equação da onda unidimensional e bidimensional: um estudo das soluções analíticas
(Universidade Federal de São CarlosUFSCarPrograma de Mestrado Profissional em Matemática em Rede Nacional - PROFMATCâmpus São Carlos, 2021-02-19)
Waves are disturbances in a medium, which move or propagate themselves in space, transporting energy from one point to another. They can be: mechanical waves, electromagnetic waves or matter waves. The theme involving waves ...

Optimal control of infinite dimensional bilinear systems: application to the heat and wave equations
(Springer Verlag, 2018)
In this paper we consider second order optimality conditions for a bilinear optimal control problem governed by a strongly continuous semigroup operator, the control entering linearly in the cost function. We derive first ...
Diffusion of elastic waves in a two dimensional continuum with a random distribution of screw dislocations
(Elsevier, 2017)
We study the diffusion of anti-plane elastic waves in a two dimensional continuum by many, randomly placed, screw dislocations. Building on a previously developed theory for coherent propagation of such waves, the incoherent ...
